BMJ Open is an online, open access journal, dedicated to publishing medical research from all disciplines and therapeutic areas. The
journal publishes all research study types, from study protocols to phase I trials to meta-analyses, including small, specialist
studies, and negative studies. Publishing procedures are built around fully open peer review and continuous publication, publishing
research online as soon as the article is ready.

BMJ Open aims to promote transparency in the publication process by publishing reviewer reports and previous versions of manuscripts
as pre-publication histories. Authors are asked to pay article-publishing charges on acceptance; the ability to pay does not
influence editorial decisions. All papers are included in MEDLINE/PubMed and Science Citation Index Expanded (Web of Science).

Impact Factor: 2.562
